Question

A magnesium sulfate solution taken orally can cause a net movement of water into the large intestine, which results from water molecules diffusing through
aquaporins embedded in the cells of the intestinal lining.
By which of the following mechanisms do the water molecules most likely move into the large intestine?

Answer 1

Answer:

Water moves into the large intestine by the process of osmosis.  

Explanation:

Water that moves into the large intestine comes from the food that we consume to derive energy. Food is broken down by process of chewing action taking place in the mouth. It then reaches the small intestine by peristalsis.  

Various actions aided by digestive enzymes and hydrochloric acid digests the food and it is then absorbed by small finger-like projection called villi in the small intestine. The absorption is facilitated by diffusion. The remains are then passed on to the large intestine.  

It absorbs a major percentage of water from this. The absorption takes place through osmosis by which difference in concentration of water inside and outside the large intestine enables the movement of water into it.
